An organic-soluble π-conjugated [1]rotaxane has been synthesized by intramolecular self-inclusion of a lipophilic permethylated α-cyclodextrin bearing a rigid π-conjugated system as a guest moiety. End-capping has been achieved successfully by connecting an aniline moiety without using bulky stoppers. The structure of the [1]rotaxane was determined by 2D NMR spectroscopy.
